Does anyone know of a utility or perl script help me print out source code in a green bar style ala old dot matrix fan-fold striped paper (but on a laser printer)?

I find reading/parsing source code a lot faster if alternate lines were different shades.

I've considered writing something like this myself, outputting html and then printing that from a browser but html doesn't handle multiple spaces/tabs literally eg. if you have 2 or more spaces it just shows up as one. but if you use "pre" tags long lines won't wrap.
